Abstract

La présente invention concerne un procédé permettant de stériliser des matériaux, en particulier des polymères, destinés à l'administration de médicaments ou à être implantés. Selon le procédé de l'invention, on traite le matériau avec un fluide supercritique de dioxyde de carbone à des pressions comprises entre 2000 et 3000 psi (140 et 210 bar) et à des températures comprises de préférence entre 30 et 45 °C pendant des périodes de 20 minutes à six heures, de préférence entre 30 minutes et 2 heures. Il a été découvert que l'agitation, l'établissement de cycles de pression et la présence d'eau améliorent le procédé de stérilisation, qui stimule la diffusion du fluide supercritique de dioxyde de carbone dans les cellules des micro-organismes, altérant le pH de ces dernières et les tuant. L'amplitude et la fréquence des différents cycles de pression, ainsi que la durée et la température du processus, peuvent varier selon le type et la forme du matériau à stériliser et le type d'organismes à neutraliser.
